[Xen-devel] Re: [PATCH] xend: PV machines have no ioemu network

Ians wants to keep changes from upstream qemu as small as possible in
those files shared with qemu. I think this is the main reason why he
didn't do it, and as long as slirp was compiled it just worked.
Additionally, specifying no -net parameter always meant -net nic -net
user for qemu, so we would not only change common code, but also the
semantics of the command line parameters. I think this is even worse.
If you've disabled slirp then "-net user" doesn't work; it would be
pretty silly for qemu to default to using "-net user" if it can't
possibly work. I think my patch is a bugfix for base qemu.
The right thing to do is to specify -net none from xend, IMHO.
Yes, that makes sense anyway.

xend: PV machines have no ioemu network
In the command line parameters of qemu-dm, xend should specify -net none
for PV machines. qemu-dm will assume -net nic -net user otherwise, which
fails now because slirp is no longer compiled in.
